Rainwater can certainly be stored underground, or under cover of some sort. Farmers lose a lot of water in irrigation areas from evaporation out of open water channels. Those that have been covered, or piped, save a lot of water. Crops really have to be watered from ground level. It would be possible in a small garden to have watering pipes under the surface, but farmers could never justify the expense.
Rainwater from thunderstorms can make its way underground and raise the water table.
The area underground that rainwater passes through is called the "unsaturated zone" or "vadose zone." This zone lies between the ground surface and the water table, and it allows rainwater to percolate through soil and rock.
An underground water storage is called a cistern. It is a structure used to collect and store rainwater or groundwater for later use. Cisterns can range in size from small containers to large underground tanks.
The purpose of a gutter drain underground is to collect rainwater from the gutters on a building and direct it away from the foundation. This helps in managing rainwater runoff effectively by preventing water from pooling around the building, which can cause damage to the foundation and basement. The underground drain carries the water to a safe location, such as a storm drain or a designated drainage area, where it can be safely dispersed without causing harm to the property.

the rain water is soaked up and held underground in the porous limestone floating on top of salt water.
The area underground where rainwater collects in the spaces between rock particles is called the "zone of saturation" or the "water table." This is where groundwater accumulates and flows through the pores and spaces in the rock or sediment.
One way to guide rainwater underground is to install a French drain, which involves digging a trench and placing a perforated pipe surrounded by gravel to help channel water away from an area. Another method is to create a rain garden, where you plant vegetation in a sunken area that can absorb and filter rainwater before it percolates into the ground. Proper grading of the land can also help direct rainwater towards areas where it can infiltrate the soil.
Dont assume underground water is safe. There are so many chemicals that are disposed of in water that it can leech underground and contaminate underground water. If you have found what you think is a good natural water source, have it tested to see how safe it is before you use it to drink or water crops.
Water harvesting is a method of collecting rainwater in storage tanks or pits which are dug underground; the purpose is to store the water for future use in irrigation or to increase the water table.
Acid in the rainwater causes limestone to dissolve, leaving open spaces, or caves.
Rainwater can infiltrate underground through soil pores and cracks in rock formations. It can then percolate through soil layers until it reaches the water table, where it becomes groundwater. This process is part of the natural water cycle.
